JEL3LQW TILE BUILDING BLOCK.

Application filed April 12,

- and declare the following to be a full, clear,

and exact description oi the same, such as will enable others skilled inthe art to which it pertains to make and use the same, reference beinghad to the accompanying draw- .g

in s, which form a part of this specification.

@ly invention relates to a hollow tile building element or block, shownin the accompanying drawings and more particularly described in thefollowing specification and claims.

The primary object of thisinvention is to provide a building block whichmay be constructed of any suitable plastic material but which ispreferably formed of clay that it maymore closely represent brick whichthe outer face of the block is grooved to repremnt.

A further object of this invention is to provide a building element withan interlocking joint at each end of the block adapted to co-operatewith similar blocks, whereby it may present the appearance of a brickwall of usual construction.

A further object of the invention is to provide for retouching allexterior mortar joints of the block, either real or imitation, so as togive the'appearance of a brick wall 7 of usual construction.

A further object of the invention is to provide a building elementrepresenting the equivalent of a plurality of bricks with an integralhollow tilebaeking, thereby greatly reducing the cost of material andlabor involved over a wall or" like character formed of separate brickunits of usual construction.

Another object of the invention is to provide a building element havingan interlocking or dove-tailed joint with a slightly arc-shaped surfacethat it may be rapidly formed by a rotary cutting knife in themanufacture of the block.

A further object is to provide a building 1922. Serial in. 551,805.

'element with interlocking crenelated portions having a relatively broadbase adjacent the body of the block converging to a blunt outer edge toprovide for maximum strength with a minimum mortar surface.

A further object of the invention is to provide a block having a minimumarticulating surface, thereby reducing the amount of mortar required forthe joints, and the labor necessary for fitting the blocks toether.

A further object of the invention is to provide the ends of the blockswith a plurality of vertically disposed opposing grooves for receivingliquid or plastic mortar, the purpose being to break joints between. theblocks, and to secure them in place, the construction being such thatthe grooves in the blocks register with the partition walls in theblocks beneath, thereby forming a floor to receive the mortar pouredinto the grooves of the superimposed blocks.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention further resides in the combinationand details of construction hereinafter described and claimed it beingunderstood that changes may be made in the precise embodiment of theinvention herein disclosed without departing from the spirit of thesame.

in the drawings accompanying this specification: I

Figure 2 is a fragmentary perspective view showing the rear of the wallwhich may be grooved to represent a brick face for use in constructingbasement walls, garages, or wherever it may be desired to have an innersurface of finished brick.

Figure 3 is a perspective view of one of the building elements.

buil ing a wall.

Figure 5 is a fragmentary end view of the block showing the interlockingjoint and one of the vertical rooves at the end of the building elementfil ed with mortar.

Referring now to the letters of reference placed upon the drawings:

A, denotes a building block preferably formed of tile, it may however bemade of any plastic material adapted for the pur-' pose. l3, indicatesgrooves in the face of the block of a character to represent-a pluralitof bricks as ordinarily arranged in C, are interlocking projectingportions spaced apart and relatively broad adjacent the body of theblock and tapering toward a blunt outer end. The interlocking portions Care ada ted to articulate with correspondingily ormed recesses D in theadj aoent bloc In the embodiment shown in the drawings the crenelatedends of the block are preferably arc-shaped at the back of theprojecting portions as this form lends itself to their rapid formationby a suitable rotary cutter. It owever will. be obvious that the rearfaces of the interlocking portions of the block may be flat ifpreferred. f

E, denotes a pluralit of vertical grooves in the ends of the blocadapted to register withthe grooves in the ad acent block to form achannel to receiveliquid mortar or cement. The grooves E are so spacedthat they are adapted to register with the partition walls A in theblock beneath which thus serves as a floor for the mortar poured intothe grooves in the su erimposed blocks. F, denotes mortar lodged in thegrooves outlining the bricks that the block may more perfectly presentthe appearance of an ordinarily constructed brick wall.

- In erecting the wall mortar may be spread upon the ed es and face ofthe interlocking portlons an also upon the edges of the partition wallsof the-hollow block. Attention is especially directed to the fact that arela tively small amount of mortar is re uired to efi'ect a suitablebond between the uilding elements, while the peculiar form of theinterlocking ends in conjunction with the mortar filled vertical groovesprovides a joint through which air cannot readily penetrate.-

Having thus described my invention what I claim is:

1. In a building element of the character described. a hollow blockgrooved upon its outer face to represent a plurality of superimposedbricks with a plurality of interlocking projecting. portions extendingfrom the end of each block adjacent to its outer face said rojectinportions having a relatlvely widg' basef-a jacent the block andtapairing in a blunt outer end said projecting with recesses 1n theortions alternatin ody of the block s aped to receive like ines esdescribed, a hollow block scored upon its outer face to represent aplurality of superimposed bricks with a plurality of interlockingarc-shaped projecting portions extending from each end of the blockadjacent to its outer face and alternating with recesses adapted toreceive the interlocking arc-shaped projecting portions. of a similarblock placed in adjacent relation.

3. In a building element of the character described, a hollow blockscored upon its outer face to represent a plurality of superimposedblocks with a plurality of tapering interlocking projecting portionsextending from each end of the block adjacent to its outer face andalternating with a plurality of recesses adapted to co-ordinate withlike tapering projecting portions of a similarblock placed in adjacentrelation and a plurality of vertical grooves formed in the ends of theblock between the tapering pro'ecting interlocking portions and therear. ace of the block. i a

4. In a building element of thecharacter described, a hollow blockrooved-fupon its outer face to represent a p urality of en erimposedbricks with a plurality of we geshaped interlocking projecting portionsextending from each end of the block adjacent its outer face andalternating with recesses in the body of the block adapted to receivethe projecting interlocking portions of a similar block placed inadjacent relation and a filling of mortar or cement lodged in the facegrooves of the blockwhereby said block may more closely resemble a wallformed of a plurality of separate bricks held together by mortar.

5. Ina building element of the character described, a hollow blockscored u on its outer face to represent a plurality 0 superimposedbricks and to receive a filling of mortar, a mortar filling for saidgrooves, said blocks provided with a plurality of interlocking wedgeshaped projecting portions extending from each end of the block, andalternating with recesses in the body of the block adapted to registerwith the corresponding projecting wedge-shaped interlocking portions ofa similar block placed in adjacent relation, said block having at eachend a plurality of vertically disposed the block,.said grooves beingadapted to re ister with like grooves in the adjacent bloc whereby the'oints between the blocks may be sealed by fi ling said grooves withmortar.

6. In a building element of the character described, a hollow blockgrooved upon its outer and inner surfaces to represent a plu- Leas es g3rality of superimposed bricks and to receive tions of a similar blockplaced in adjacent relation. 10

In testimony whereof, I sign this specification in the presence of twowitnesses.
